i am trying to filter the list from the array of structs to display only values needed, what went wrong here https://trycf.com/gist/50f3aeab1dabcdc78b722f3d02dd154a/acf?theme=monokai

arrayFilter is your friend here

also, you are missing a closing a

)

in your IF. You have:

if(listfindnocase(lstremovekeys,key.address_state) {

SHOULD BE

if(listfindnocase(lstremovekeys,key.address_state)) {

Something like:

data = [
     { address_city : "Washington" , address_state : "DC" } ,
     { address_city : "New York" , address_state : "NY" } ,
     { address_city : "Miami" , address_state : "FL" }
] ;

lstremovekeys = 'NY';

newData = arrayFilter( data, function( item, index ){
    return listFindNoCase( lstremovekeys, item.address_state ) ? false : true;
} );

writeDump(newData);

@gsr excellent work giving us some code this time. But make sure to run it before showing it to us 😉 That code doesn't compile, as @Adam Palcich said. And instead of "what went wrong here", tell us exactly what yer expecting to see, and what yer seeing instead. "it's still got washington, but it should have been removed" or something.
